Abstract: | We measured and demonstrated the great advantages of embedded film capacitors in reducing power/ground inductive impedance and the suppression of SSN at frequencies up to 3 GHz for high-performance multilayer packages and PCBs. Eight-layer test PCBs were fabricated, and their inductive power/ground network impedances were measured as a function of film thickness, via distribution, and combined use with discrete decoupling capacitors, using a two-port self-impedance measurement method. This successfully demonstrated that the power/ground inductive impedance was reduced from 270 pH to 106 pH simply by using an embedded film capacitor instead of 16 discrete decoupling capacitors. |
